Passivation device for mechanical manufacturing

Abstract

The invention discloses a passivation device for mechanical manufacturing, and relates to the technical field of passivation. The passivation device comprises a box body, a motor is fixedly connected to the bottom of the inner wall of the box body, a telescopic rod is fixedly connected to one end of the motor, and a rotating mixing anti-adhesion mechanism is arranged in the box body. According to the passivation device for mechanical manufacturing, the rotating mixing anti-adhesion mechanism is arranged, so that through back-and-forth forward and backward rotation of a passivation pool, a circular groove and an arc-shaped groove in the passivation pool can stir and mix passivation liquid in the passivation pool in real time while the circular groove and the arc-shaped groove do not make contact with a part being passivated, and the situation that the surface of the part is damaged due to the fact that a stirring rod protruding during mixing and stirring touches the part being passivated is avoided; the rotating mixing anti-adhesion mechanism is arranged, so that a large amount of precipitates which are rotationally thrown to the passivation solution through rotating centrifugal force are thrown to adhere to the surface of an arc-shaped plate and are shaken off, and the uniformity of the passivation solution is higher.

Description

technical field [0001] The invention relates to the technical field of passivation, in particular to a passivation device for mechanical manufacturing. Background technique [0002] Passivation refers to the process of metal oxidation by strong oxidants or electrochemical methods to make the surface inactive, that is, passivation. It is a method to transform the metal surface into a state that is not easy to be oxidized and delay the corrosion rate of the metal. In addition, the phenomenon of an active metal or alloy in which the chemical activity is greatly reduced and becomes a noble metal state is also called passivation. At present, when passivating and mixing the inside of the passivation tank, the centrifugal force of stirring often leads to uneven distribution of chromium ions in the passivation tank, which tend to adhere to the inner wall of the passivation tank, and precipitate crystals will appear at the bottom of the tank, resulting in The passivation of the work...
